IVILLIAM PATTERSON, OF SAN FRANCISCO, CALIFORNIA.

HINGE.

SPECIFICATION forming part of Letters Patent No. 292,574, dated January 29, 1884,

Application filed October 25, 1883. (No model.)

It consists of a cup or sleeve surrounding.

the pintle and extending a-short distance upward from the shoulder upon which the socket rests. The socket has its lower end formed with a channel or groove between itself and the plate or leaf, so that it can extend down into the cup, the edges of which thus extend up linto the groove. The socket is open at the top to admit oil, and an ornamental screw-cap closes it.

, Referring to the accompanying drawings for a more complete explanation of my invention,

Figure l is a view of my hinge and oiling atl tachment. Fig. 2 is a vertical section, and

' Fig. 3 is a perspective view in a modified form.

A and B are two leaves of a hinge. The leaf A has a cylindrical projection, O, upon the lower half of one edge, and the pintle D extends upward from its center. a cylindrical projection, E, from the upper half of its corresponding edge, andthis pro- 3 5 jection is perforated longitudinally to form a socket for the pintleD. The lower end of the socket Ethus forms a shoulder, which is supported upon the part C in the manner usual to this class of hinges.

In my invention a sleeve,vF, is formed with or fixed to the part C, projecting upward from the shoulder upon which the socket E rests, and it is made of a sufficient size to allow the socketto turn within it. In the present case the sleeve'h` is shown of larger diameter than the part E 5 but the sleeve will usually be made The leaf B has of the same diameter, and the lower end of E and have a shoulder just at its top, as shown in Fig. 3, the two parts presenting an even continuous outline. In order to allow the socket to-V pass down into this sleeve or cup when placed upon the pintle` a groove, a, is formed between it and the leaf, of which it forms a part, this groove being as long as the depth of the cup. The socket for the pintle, instead of being made only of sufficient depth to just receive the pintle, is continued up to the top, thus forming an opening, through which oil may be introduced. An ornamental cap forms the finish for each end of the parts C and E, and the upper one, G, screws into the hole at` the top, and thus forms a stopper for it.

-I am aware that'hinges have been made with a cup at the lower end of the pintle, to hold oil, and that in a hinge having twofprojections from one leaf, inclosing a central one from the other, the pin passing through to unite them has been channeled or grooved to allow oil to ilow down into the cup.` I do not,

therefore, claim such a device.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a hinge composed of two leaves, one of` which carries a single fixed pintle and the other a socket to fit over the said pintle, an vextension or. cup surrounding the pintle, in combination with the socket E, in which is fitted into the top a removable tip, G, said socket being provided with a slot, a, formed between its lower end and the leaf, whereby the socket-is allowed to enter the cup and turn therein, substantially as herein described, and for the purpose set forth.
